可以在hardwareSerial.h中修改。 #define SERIAL_RX_BUFFER_SIZE 512 // 接收缓冲区 #defind SERIAL_TX_BUFFER_SIZE 512 // 发送缓冲区 对于软串口, 也有对应的宏定义方式来修改,也可以在SoftwareSerial中修改。 #define _SS_MAX_RX_BUFF 512 // 接收缓冲区 #define _SS_MAX_TX_BUFF 512 // 发送缓冲区 ...
Serial.read() 描述:读取串口数据,一次读一个字符,读完后删除已读数据。 原型:Serial.read() 参数:无。 返回值:返回串口缓存中第一个可读字节,当没有可读数据时返回-1,整数类型。 Serial.readBytes() 描述:从串口读取指定长度的字符到缓存数组。 原型:Serial.readBytes(buffer, length) 参数: buffer:缓存变量。
Arduino开发环境怎么安装SoftwareSerial库 arduino 安装库 当你轻松地使用Arduino软件(IDE)及其内置功能后,你可能想通过其他库来扩展Arduino的性能。 什么是库? 库是代码的集合,使你可以轻松连接并使用传感器、显示屏和模块等等。例如,内置LiquidCrystal库可以实现与字符LCD显示器之间的轻松沟通。网上有很多其他的库可以下载...
SoftwareSerial Library 现有的Arduino硬件支持引脚0和1(通过USB连接到到电脑)进行串行通信。串行通过一个称为 UART 的硬件(芯片内置)进行。这个硬件允许ATMEGA芯片接收串行通信,即使芯片在进行其他工作,只要有64个字节的串行缓冲器的储存空间即可。 使用软件的串口功能(因此称为“SoftwareSerial”,即“软串口”),现有的...

The SoftwareSerial library bundled with Arduino has had significant enhancements; see Recipes4.13and4.14. ASerial.peekfunctionhas been added to let you ‘peek’ at the next character in the receive buffer. UnlikeSerial.read, the character is not removed from the buffer withSerial.peek. ...
the default baudrate has been set to 9600 bps in favor of plug-and-play. You may reconfigure the baudrate both in source code and in Device Manager. At a baudrate of 115200 bps, a packet of 66 bytes (594 bits), despite exceeding the default buffer size of serial (64 bytes) on Ar...
